GILBERT S. CRYNE, OF FOND DU LAG, WISCONSIN, ASSIGNOE OF ONE-HALF HIS RIGHT TO BENJAMIN F. MOOR-E, OF SAME PLACE.

IMPROVEMENT IN END-GATES FOR WAGONS.

Specification forming part of Letters Patent No. 210,756, dated December 10, 1878; application led October 2l, i878.

To all whom it may concern:

Beit known that I, GILBERT S. GRYNE, of Fond du Lac, Fond du Lac county, Visconsin, have invented a new and useful Improvement in Dump-Gates, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Thenature and object of my invention are the con struction of a dump-gate from theV ordinary tail-board by dividing it into two parts of peculiar shape, o: y, with double hinge-joints B, ball-hinges b l), grooved back piece, A a, and T- button C, as shown in drawings.

The drawings show as follows: Figure 1, a general view of my device closed 5 Fig. 2, view of same open; Fig. 3, back view of same.

A is the back piece; a, the rod-groove therein. B B is the double hinge-joint; b l), the ball-hinges. G is the T- button; w, the bifurcated section; y, the ton gue-section of the tailboard.

I am aware there has been a tail-board in use cut in two L- shaped pieces, connected with single rod hinge -joint. These Y'depend only upon their mitered edges for stiffness, and, having only one hinge -joint, 'warp and spread apart, and are latched by a large clumsy device.

My device is constructed as follows: I cut an ordinary tail-board in two sections-one, x, forming a fork, the other, y, a tongue. Ihin ge :iue pieces with ball-hinges b b at the points It will be evident that the fork it, claspin g the tongue y, will prevent warping or spreading of the hin ge-j oi nts, and render eftective the simpleball-hinges l) b. These balls are dropped into bores sunk through the prongs of x to and slightly into the tongue y, and rimmed slightly at joints. The bores are then plugged.

I strengthen the fork-shaped section, and support the tongue with a back piece, A, nearly covering'the pron ged part of fr.

Icut the groove a across the back piece, A, in which the tail-rod lies, and holds down the tail-board, while not interfering with its lateral movement in opening and closing.

Having thus made my tail-board strong and firm in every part, I am enabled to and do use the simple T- button G, which, by its own gravity, keeps always in place, and makes an effective and easily-worked latch.

I believe that I have thus shown an improvement in the construction of dump-gates embodyin g novelty, efficiency, and economy in their use and manufacture; and

I claim as my invention- The combination, in a dump-gate, substantially as described, of the forked and tongueshaped sections, double hinge joints, ballhinges, T- button, and grooved back piece.
